Dampening Printing Rollers

The job of dampening form rollers is to take up the fountain solution uniformly from the transfer or metering roller, transfer it to the printing form and provide a good ink-fountain solution emulsion. When a dampening film is taken up by a dampening form roller, the film is stretched, as the dampening form rollers runs much faster than the metering roller. Here, it is important that part of the fountain solution is emulsified in the ink. Thin negative lines and structures in the image are kept free of ink by the fountain solution emulsified in the ink which is released, when the emulsion separates under the pressure of the plate roller.

 In the dampening unit there are also rollers that receive the water and rollers that give the water to the printing plate. Accordingly, there may be two different dampening systems:

  • Conventional system
  • Alcolor system

 DAMPENING ROLLERS -  AquaFloEx, AquaFlo Alcohol & Water Compatible

 

Alcohol Dampening Rollers

 Alcohol Damping Roller supplies alcohol for printing objects in the Offset Printing Machine. It is having the mixture of alcohol and water in it, the percentage of alcohol and water varies for machine to machine and depends on the object to be printed. The alcohol roller is used naked or without cover. If the roller has converted from water to alcohol then the diameter should be increased.

 Ideal compound for Dampening, Pan and Metering roller for IPA, IPA-reduced and IPA-free printing. 

Suitable for Sheetfed & Webfed offset application.

BENEFITS

  • Resist wear & tear due to metering action.
  • Good and even wetting due to hydrophile (water - friendly) formulation.
  • Resists shrinking, swelling, hardening and abrasion.
  • Reduces start-up waste and achieves fine film thickness of fountain solution on plate.
  • Faster start ups due rapid attainment of the ink water balance.
  • Light roller settings.
  • Good fountain solution transferability.
  • Excellent resilience.

Inking Rollers

Inking Rollers for Better Printing

The invention relates to an inking roller for an inking unit of an offset printing press wherein the inking roller includes a number of zones arranged in the direction of the axis of rotation and at least one ink reservoir in the interior of the inking roller. In each of the number of zones, the at least one ink reservoir is connected to at least one ink exit in the circumferential surface of the inking roller. In inking units of offset printing presses, ink is frequently supplied from an ink fountain or ink reservoir to a group of inking unit rollers by means of an ink fountain roller and ink metering devices arranged along the axis of rotation of the ink fountain.

The inking rollers are normally composed by the ink ductor roller (rubber rollers that first receive the ink), the ink form rollers (rubber rollers that give the ink to the printing plate) and the distributor rollers.

INKING ROLLERS : Suitable for sheetfed application.

We at SIGMA ROLLERS have following grades to meet your requirements.

UltimaUV   :  for Hybrid Inks & UV Inks

 UltimaEx    :  for Non UV Inks

 Ultima         :  for Conventional Inks     

UltimaUV : for Hybrid Inks & UV Inks

For UV Ink applications, dimensional stability, Ink transfer and dot gain are the major Issues faced by printers today. Printers who toggle back and forth between UV and Conventional Inks sometimes needs more time before the rollers acclimatize to the new ink and begin transferring properly.

UltimaUV has exceptional quality of resistance to permeability of Ink Into pores thereby maintaining clean knap all the time. UV ink rollers are meant for exclusive printing objects, in which hybrid UV Ink can be used for better results.

 BENEFITS

Improved ink transfer

Rubber rollers used in UV printing have ink fluidity problems. With UltimaUV there is:

  • No roller surface tackiness
  • Improved Ink transfer with good film strength
  • Faster drying times

Excellent dimensional & hardness stability

For both UV ink-Conventional ink users, the rollers are subjected to instability caused by chemical changes on the surface of the rollers. UltimaUV remains extremely stable both dimensionally, as well as in hardness. The benefits are:

  • Less downtime because of quick roller resetting
  • Extended roller life
  • Shorter Wash-up times

Resistance to ink permeation

Over a period of time, rollers used In UV printing are susceptible to faster rates of ink glazing caused by the ink penetrating into the pores of rubber and filling in these pores.

  • Less Ink Glazing
  • Excellent Dot Reproduction
  • Clean velvety surface

Excellent dot reproduction

 

UltimaEx/ Ultima : for Non UV Inks/ for Conventional Inks

BENEFITS

  • Good tensile strength, better dimensional and hardness stability.
  • Resistant to oil, acrylates, abrasion and glazing.
  • Better ink storage and transferability.
  • Close Grinding tolerance results in even ink distribution.
  • Excellent resilience converts heat energy into kinetic energy.
  • Superb resistance to swelling & shrinking.

Lamination Films

Lamination is generally done on printed surface to protect it and provide it longevity. Therefore lamination films find their way into mostly print publishing and graphic art film segments. However today, lamination films are widely used for rendering beautiful textures and premium tactile feel to luxury packs as well. We supply films meant for both applications to both laminators /printers and packaging manufacturers through our network of distributors spread across the globe.

 

 

Our standard range of lamination films are used for both thermal lamination and wet lamination processes.

Thermal lamination films have extrusion coated surface with low temperature melting resin, which enables the lamination of film to paper products by heat and pressure. Our films can be used on all types of thermal laminating machines available across the world. We provide thermal lamination films in both BOPP and PET base. On the other hand, wet lamination films are suitable for conventional wet lamination done with dispersion, solvent-based, UV or special hot-melt adhesives. All lamination films used for wet lamination are pre-treated on both sides for subsequent converting (hot stamping, embossing, UV spot varnishing, etc.). The films are slip modified for high speed lamination and have good anti-static properties. The films also have excellent adhesive anchorage which in turn supports excellent bonding with paper. These films are available in BOPP base.
